FUSE CUTTER Filed Oct 17, 1938 Patented Mar. 4, 1941 UNITED STATES PATENT OFFICE 3 Claims.

My invention relates to fuse cutters and like tools, and has for its object to provide a new and highly efiicient fuse cutter for anyone using powder or dynamite for blasting.

A further object of my invention is to provide a tool which both cuts the fuse 01f, splits the end for igniting, and cuts angled notches into the side of the fuse.

A still further object is to provide a fuse cutter in which the blade will fit into a notch in the opposite side of the tool and which notch acts as a constant cleanout recess, making it unnecessary to even stop and clean the tool while in use.

A still further object is to provide a manually operated tool having a cutting blade and a receiving base, the receiving base being provided with the necessary notches or recesses for hold- 9 ing the fuse while it is being cut in its desired angles.

These objects I accomplish with the device illustrated in the accompanying drawing in which similar numerals and letters of reference indicate like parts throughout the several views and as described in the specification forming a part of this application and pointed out in the appended claims.

In the drawing, Figure l is a plan view of my fuse cutter.

Figure 2 is a face view of the fuse holding jaw of the cutter.

Figure 3 is a section on line 3- -3 of Figure 2.

Figure 4 is an end view jaw at relative positions of the two jaws before they are completely meshed.

Figure 5 is a view of a section of blasting fuse showing the cuts possible with my cutter to make a fuse spitter. 4 In the drawing in which I have shown my device, the fuse cutter is shown as made of two handles having opposed heads A and B, hingedly connected as is a common pair of pliers by a pivot rivet C.

The head A is provided with a longitudinal semi-circular central groove 1 cut lengthwise of the fiat face 8 of the head. At right angles to this groove there is another semi-oircular-groove 9 transversely of the head, and another like formed groove I0 is cut in the face 8 at an acute angle to the groove 9 bisecting the other two grooves. Entirely through the head A and centrally of the groove 1 I provide a cleaning slot II which prevents the gummy material of the fuse from clogging the tool.

The head B is formed as a cutting blade l2 which is formed centrally of the head and is adapted to fit into the slot II. This cutting blade is utilized to cut off a fuse F by placing it transversely in the groove 9. The end of the fuse is then split by placing it in the groove 1. and cutting it medially with the blade l2 to split the end of the fuse forming a slot 13 as shown in Figure 5. To make a section of fuse as a starter, it is first split and is then cut on an angle as shown at H! in Figure 5, by placing it in the cutter in the angled groove I0 and bringing the cutter blade l2 down onto the fuse cutting an angled slot [4 part way through the fuse.

One leg of the cutter or the handle of the blade B is formed into a tubular chamber 5 closed by an internally threaded screw cap 6 which chamber is provided to carry a cap reamer for use in the usual order of setting dynamite for blasting.

The operation of my invention having been 20 fully set forth above further specific details are not thought necessary.

Having thus described my invention I desire to secure by Letters Patent and claim:

1. A fuse cutter of the class described, comprising hingedly connected heads and with one 25 head formed into a cutter blade and the other head formed with a fiat surface having longitudinal, transverse and angled grooves semi-circular in form and formed inthe face of the head said grooves to receive the lower half of a fuse holding it for splitting, cutting and forming spitter slots along the edge thereof and handles to operate said heads.

2. A fuse cutter comprising two heads pivotally connected; handles for each head to engage them together; semi-circular grooves formed longitudinally, transversely and at an acute angle in the fiat surface of one head; and a cutter blade formed as an integral part of the other 0 head said cutter blade to engage and cut a fuse when laid in any of the grooves.

3. A fuse cutter comprising two coacting heads pivotally connected with one head having its face formed into a cutting blade and the other head 45 having its face formed with a flat surface in which semi-circular grooves are cut, one groove being longitudinal of the head, one transversely of the head and the other at an acute angle to the longitudinal groove said grooves to hold a fuse for cutting in any of the three positions possible; and a cleaning slot through the. bottom of the longitudinal groove said slot to provide cleaning means for the cutter blade.
